The Valuable Book EX 3 released today, and we have the full list of theme lores explained in it:

Albaz/Branded
Visas
Vaylantz
Labrynth
Runick & Generaider
Purrely
Mikanko
Vernusylph
Ninja
Rescue-ACE
Libromancer
Amazement
Lil-la-Rap
Gunkan/Suship
Sweet Room-Maid
Ultimate Slayer
Kurikara Divincarnate

The following two screenshots are from the actual book, and they are way out of context to draw any conclusions, but I’m sure someone will ask about them, so here we are:

“Introducing the stories for each theme hidden in the illustrations of OCG cards. The story of ‘Albaz’ and ‘Ecclesia’ that has been published in the Valuable Books so far will also be reaching its (temporary/for now) conclusion.”

“The foreword of a new disturbance
The Boundless Open Land”

Without further context, it’s impossible to tell if the story of the rice girl and her dragon boyfriend will continue, or they are just being overly dramatic about an open ending.
